Website Architecture for AI Search Optimization 2026
Website architecture for AI search optimization requires: (1) logical URL structure that reflects content hierarchy, (2) strategic internal linking connecting related content, (3) flat architecture keeping important pages within 3 clicks, (4) XML sitemaps for crawler discovery, and (5) fast, mobile-friendly pages. AI crawlers benefit from the same architectural best practices as traditional search crawlers, with added emphasis on content relationships and topical clustering. According to Search Engine Land, sites with optimized architecture see 25% better crawl efficiency for AI bots.
Key Takeaways
